Climbing rose plant named ‘Poulcy011’

ABSTRACT

A new garden rose plant of the climbing rose class which has abundant, pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrid.

Variety denomination: ‘Poulcy011’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of gardenrose plant that originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent,‘Pouldiram’, a rose variety by the same inventors, described andillustrated in U.S. Plant Pat. No. 12,568 issued Apr. 23, 2002.

The two parents were crossed during the summer of 1994 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety is named ‘Poulcy011’.

The new variety may be distinguished from its female seed parent by thefollowing combination of characteristics:

-   -   1. The seed parent has an upright bushy growth habit, while        ‘Poulcy011’ has a climbing growth habit.    -   2. ‘Poulcy011’ has more flower petals than the seed parent        plant.    -   3. The seed parent has red flowers while ‘Poulcy011’ has pink        flowers.

The new variety may be distinguished from its male pollen parent,‘Pouldiram’, by the following combination of characteristics:

-   -   1. ‘Pouldiram’, has white flowers while ‘Poulcy011’ has pink        flowers.    -   2. ‘Pouldiram’, has an upright and bushy growth habit, while        ‘Poulcy011’ has a climbing growth habit.    -   3. ‘Pouldiram’ has fewer flower petals than ‘Poulcy011’.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant medium pink flowers;    -   2. Vigorous, but compact growth when propagated both as a budded        rose and on its own roots.    -   3. Disease resistance;    -   4. Reduced apical dominance in flowering habit. The new variety        consistently produces flowers evenly from the lower branches to        the top of the plant.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poulcy011’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 1995 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark.

‘Poulcy011’ was selected in the spring of 1996 by the inventors as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulcy011’ by traditional budding and rootedcuttings was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in July, 1996. This initial and other subsequentasexual propagations conducted in controlled environments havedemonstrated that the characteristics of ‘Poulcy011’ are true to typeand are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulcy011’, as observed in its growthin in a field nursery in Jackson County, Oreg. Observed plants are 2years of age, and were grown on Rosa multiflora understock. Colorreferences are made using The Royal Horticultural Society (London,England) Colour Chart, 1995, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Poulvam’, a rose variety from the same inventors described andillustrated in U.S. Plant patent application Ser. No. 10/269,793 datedOct. 10, 2002, are compared to ‘Poulcy011’ in Chart 1.
